subtree(3p/cgit): merge cgit-pink into depot cgit

Browse source 
cgit-pink is a maintained fork of cgit that follows upstream git more
closely and already contains a lot of patches we already had applied.
Consequently, it seems sensible it becomes our future upstream, we may
even be able to upstream some of our custom, less invasive patches.

cgit - CGI for Git

cgit-pink - CGI for Git
=======================
This is an attempt to create a fast web interface for the Git SCM, using a

This is a fork of cgit, an attempt to create a fast web interface
for the Git SCM, using a built-in cache to decrease server I/O
pressure.
Installation
------------
@ -32,18 +33,6 @@ This will install `cgit.cgi` and `cgit.css` into `/var/www/htdocs/cgit`. You
can configure this location (and a few other things) by providing a `cgit.conf`
file (see the Makefile for details).
If you'd like to compile without Lua support, you may use:
$ make NO_LUA=1
And if you'd like to specify a Lua implementation, you may use:
$ make LUA_PKGCONFIG=lua5.1
If this is not specified, the Lua implementation will be auto-detected,
preferring LuaJIT if many are present. Acceptable values are generally "lua",
"luajit", "lua5.1", and "lua5.2".

This is called upon activation of the filter for a particular
